Abstract :
In this study, biomarker analyses were conducted on four condensate samples recovered from Kafr El
Sheikh and Abu Madi Reservoirs in Abu Qir concession, NW offshore Nile Delta. Moreover, according
to the obtained results, it was indicated that the condensates are genetically related, and they were
derived mainly from clay-rich source rocks of mixed organic sources, with significant input of terrestrial
organic sources, deposited in low saline fluvio-deltaic environment. These conclusions are supported by
the relative abundance of both C29 and C27 regular steranes, high diasteranes, and Pr /Ph ratios and the
lowC29norhopane relative to C30hopane, low isoprenoids/n-alkanes ratios and lack of gammacerane. In
addition, biomarker maturity indicators suggested that the condensates were sourced from early mature
source rocks. Finally, geochemical and isotopic data from gases indicated that Abu Qir gases are of
thermogenic origin generated from source rocks with mixed types II/III kerogens.
